I have ordered frag packs from RM 3 times in the past and was glad with the colorful assortments they send. However, they send you wild colony frags that are freshly cut. While I have had good success with many frags, the loss is greater. I recently tried Dr. Mac's and received a less colorful assortment (mostly tan,pink,brownish). The good thing is that the frags are noticeably encrusting, ie, not freshly cut. They are now starting to color up under my 250W. The loss is much less with their frags. I would order from either again. I would probably go with Dr. Macs if I were you, just to get a feel for SPS care. The loss from RM frags may be discouraging for a newbie (even for me). Just my .02
